Teamsters went on strike Tuesday against a private company called C.R.P. Sanitation, affecting garbage pickup in four Westchester communities.

There are 70 members of Teamsters Local 813 striking against C.R.P. Sanitation. They walked the picket line outside the company?s headquarters. The workers have complained they've been working without a contract since the end of 2005. The company has contracts to collect municipal trash in Yorktown, Ossining, Mount Pleasant and Rye Brook. The union's business agent says wages and benefits are the main issues.

According to C.R.P. officials, they are using managers and replacement workers to collect garbage during the strike. Union members plan to picket construction and other commercial sites where C.R.P. makes pickups.
